I METAL WINDOW FRAME AND SASH.

Application filed December My invention is particularly applicable to metallic frames for what are known as double hung windows including a. jamb frame in which two sash frames are mounted to reciprocate parallel with each other.

As hereinafter described, my invention repreferably formed of sheet zinc with iii-' 15 wardly curled resilient edges which form water-tight joints in contact with vertical hollow guide flanges, also preferably formed of sheet zine; the latter serving as a facing for the jamb, covering openings through 20 which the sash weights may be removed.

Such construction and arrangement is more economical than the provision of separate weather stripping which is characteristic of the prior art.

As ordinarily constructed, a complete metallic window, including a frame and sashes, costs thirty dollars or more, which is doublethe cost of wooden structures for the same purpose. Therefore, this invention has been so designed and is adapted for such economical manufacture as to approximate the cost of such wooden structures.

My invention includes the various novel features of construction and arrangement 85 hereinafter more definitely specified.

In said drawings; Fig. I is an outside elevation of a window frame and'sashes embodying my invention.

Fig. II is a fragmentary plan sectional 40 view, taken on the line II, II in Fig. I.

Fig. III is a vertical sectional view of said structure, taken on the line III, III in Fig. I, in the direction of the arrows on said line.

Referring to Fig. I; the window frame includes the lintel 1, opposite jambs 2, and

sill 3 in which the upper sash 5 and lower sash 6 are hung for vertical reciprocation. Each of said jambs 2 is formed of a single 60 sheet of metal, for'instance, galvanized iron,

folded to form a recess 8 in the inner vertical face of the jamb and with its edges presented in flanges 9 extending outwardly from the outer face of the jamb and there 10, 1925. Serial No. 74,446.

engaging between them the partition plate 10 forming separate compartments for the respective sash weights 11 and 12. The inner wall of-said recess has the opening 13 therein, extending from a short distance above said sill 3, to such height as to permit removal of said weights 11 and 12 through it, as indicated by dotted lines in Fig. III. However, that opening is normally closed by two vertically extending plates 14: and 15 respectively at the upper and lower portions of the jamb, as indicated in Fig. III and which are of substantially the same con figuration but formed separately to facilitate their insertion and removal, each being adapted to be rigidly, but detachably, con-.

nected with the jamb by screws 16', preferably having flat heads seated in depressions in said plates and in screw threaded engagement with the inner walls of said jambs 2, as indicated in Fig. II. Said plates may be abutted, or overlapped, at the dash line indicated adjacent to the top of said opening 13 in Fig. III.

Each of said plates 14; and 15 has two hollow vertical ridges 17 and 18 which respectively extend within the recesses 20 and 21 of said sashes 5 and 6.

Each of said sash frames 5 and 6 is also formed of sheets of metal, preferably galvamzecl iron, folded to form said recesses 20 and 21 with the edges of each sheet interengaged at the outerfaces thereof, as shown in Fig. II. The opposite inner edge of each of said frames is folded to form respective hollow flanges 23 and 24 in which the panes of glass 25 and 26 are set in cement 27 and 28.

Said sash frame recesses 20 and 21 are lined with hollow bars 30 and 31, convenently formed of pressed sheet zinc having inwardly curled resilient flexible portions 32 and 33 respectively bearing upon said hollow ridges 17 and 18, in sliding contact and forming weather proof joints th'erewith.

Said lintel 1 is formed of a sheet of metal, preferably galvanized iron, with its opposite edges folded together to form the flange 34: extending upwardly at the outer face of the window frame and adapted to overlap the wall 36 in which the frame is set. The lower edge of said lintel 1 is provided with the hollow flan e 37 forming a pendent edge from which rain will drip instead of flow- I 0ve'rlapping sash members 63 ing inward upon the under surface of said lintel. Said lintel is also provided with the hollow ridge 39 adapted to extend within the recess 40 ofthe top rail 41 of said sash 5, where it is engaged by the resilient curled edge 43 of a sheet of metal, preferably galvanized iron, from which said rail is formed as shown in Fig. III. Theopposite inner edge of said top sash rail 41 is provided with an inwardly extending hollow flange 45 similarto the hollow flanges 23 and adapted to hold said glass 25 set in said cement 27.

Said sill 3 is also conveniently formed of a single sheet of metal having its opposlte edges inwardly turned to engage said wall 36; said sill havingthe hollow ridge 47 extending upwardly therefrom parallel wlth the upwardly inclined inner corner 48 of said sill; forming a gutter 49 for reception of moisture condensed upon the inner faces of said sash, which is permitted to escape through notches 50 in said ridge 47, the latter being filled with solder 51 at said notches to prevent access of such water of condensation to the interior of said sill. v

As shown in Fig. III, said sill ridge 47 projects'upwardly into the recess 53 of the hollow lower sash frame rail 54 which is formed of a single piece of metal like the top rail'41 of the upper sash frame 5 and has the inwardly extending flange 56 to receive the glass 26 set in cement 28. Said piece'has one edge curled, at 58, for resilient flexible contact with said sill ridge 47 toform a weather proof joint therewith. Said lower sash rail 54 is conveniently provided with one or more handles 60, formed of strips'of metal welded or otherwise secured thereto.

The bottom rail 61' of the top sash 5, is also formed of a single sheet of metal folded to form the upwardly extending hollow flange 62 which holds said glass 25 mounted in said cement 27. However, one edge of said sheet metal forming said'sash rail 61 is folded to depend from said flange 62 in spaced relation with the inner face of said sash and form a resilient bight 63 having its opposite faces inwardly converged to receive between themthe pendent edge. 65 of the sheet metal plate forming 'thetop rail 66 of the bottom sash 6 which is similarly folded to form the pendent hollow flange 67 to hold the glass 26 set in cement 28. It is to be understood that the. joint between said members 63 and issubstantially weather tight.

. secured thereto; which Said top rail '66 of the bottom sash '6 isprovided at its inner face with a plate 69 conveniently located intermediate of the 5 width of saidsash and welded or otherwise plate has an open in'gthereth'rough for the plunger 70 which is provided with the knob 71 bywhich it may be'thrust outwardly to extend through said and 65 to in- 81' extend downwardly te rlock them. -"I'-Iowever, said plunger 70 iv normally held, in the unlocked position. shown in Fig. III by the spring 73 which eh- I circles it, within said sash rail 66. and bears against, the cross pin, 74 which extends 70 through said plunger 70. Said plunger 70 is also provided with the cross pin 76 which is normally presented exterior to said plate 69, when said plunger 70 is in the unlocked position shown. However. said plate .69 has 75 diametrically opposite radial slots 78 extendtating it to again-present said pin 76 in reg- 85 v istry with said slots 78; in Which position said plunger may be thrust outward by its spring 73 to the positionshown.

Said weights 11 and 12 are pendent from flexible connectors80 and 81 extending over pulleys 82 and 83 in casings 84 and 85 placed in said lintel 1, as indicated in Figs. I and III; so that said flexible connectors 80 and through suitable openings in the underface of said lintel di rectly into the hollow sash bars 30 and 31 in which they are detachably connected with the respective sashes 5 and 6 by any suitable means. For instance, said connectors may said 80 be cords, provided with knots at their ends extending within the hollows ofsaid sashes 5 and 6, through suitable openings in said bars 30 and 31. r I

It is to be noted that the construction and arangementabove described requires less metal for its formation, and is consequently less costly to manufacture, than similar structures of the prior art; that said face plates 14 and 15, with their hollow ridges 17 and 18, serve three purposes; first, as closures, second, as guide railsyand third, as weathering devices. That the configuration of the same efiects a radical change from the weather stripping of the prior art, in that the area of sliding contact is reduced-to narrow lines, and with air spaces between those tofore,

Therefore, I do not'desire to limit myself tothe precise details of construction and arrangement herein set forth as it is obvious be made smaller, and ,to'require less metal in the weights,'than hereand impose less strain on the flexible 126 connectors supporting them.

including the disposal 3 that'various modifications may be' made 130 therein without departing from the essential features of my invention as defined in the appended claims.

I claim:
